KNEADING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 793,283, dated June 27,1905.

Application tiled December '7, 1903. Serial No. 184,180.

To all II77I/07H/ it may concern:

Be it known that l, Jouaim DIESGIIBURG, a subject of the Emperor ofGermany, residing at Echternach, in the Grand Duchy of Luxemburg,Germany, have invented a new and useful improvement inKneading-Machines, of which the following is a specification.

My invention relates to a machine for kneading dough; and the object ofthe invention is to produce a machine of this character which willfacilitate bread and cake making.

My invention consists in the novel features of construction andcombination of parts hereinafter described, particularly pointed out inthe claims, and shown in the accompanying drawings.

Figure l is a perspective view of my machine. Fig. 2 is a longitudinalsection through the machine, parts being shown in elevation. Fig. 3 is adetail view, partly in elevation, showing the guide-pin lifted from thespiral groove. Fig. 4 is a detail view, partly in section and at rightangles to the view in Fig. 3, showing the pin in engagement with thegroove. Fig. 5 is a plan view showing in detail the construction ofparts located at the right-hand end of the frame shown in Fig. 1. Fig. 6is a detail sectional view of the gearwheel which meshes with theworm-gear shown in Fig. 5. Fig. 7 is a detail view, partly in section,showing the kneading-arms.

in constructing my device I employ a table A, having suitable side andend pieces and having central transverse cross-pieces A. Thecross-pieces A extend downward below the plane of the table, which iscut out between them. Suitable side and bottom pieces are arranged inconnection with the pieces A, whereby is formed a centralkneading-receptacle B, supported by the table A.

Extending below the bottom of the table proper, but passing transversethrough the receptacle B, is a shaft B, longitudinallygrooved adjacentone end and having a double spiral groove B" formed MlJtICOIlb theopposite end. On the shaft in the receptacle are "l"l l**l t ll"C(" laiiangei Sit L sue wo co ais J, eaci carrying oppositely-dlsposed arms,one arm of each collar being straight and the other forming a compoundcurve. The arms U" of the collar 0 are solid, while the arms G of thecollar U are bifurcated or slotted, as is clearly shown in Fig. 2.

To drive the shaft B and the arms C and C, a shaft 1) is journaled inthe table adjacent and at right angles to the longitudinallyslottedportion of the shaft B, and a handwheel I) is secured to the outerprojecting end' of this shaft. On this shaft, arranged within a suitablecasing D is a worm-gear D. This worm-gear meshes with a gearwhecl B,splined on the shaft B.

The operation of the machine will beobvious. Dough to be kneaded isplaced in the receptacle B and is worked and mixed by means of therotation of the arms C" and C". To further effect a thorough kneading ofthe dough by giving a longitudinal movement to the shaft B simultaneouswith its rotation, I arrange a pin E in a bracket F, which pin isenlarged and curved at its lower end to [it in the spiral groove B Thepin has two annular grooves E formed on its upper portion. Theshaft B isjournaled in the lower portion of the bracket F, and a spring is securedat its lower end to the bracket, as at H, and the upper end of thisspring is adapted to engage one of the grooves E, the upper portion ofthe spring H being bent and extended through an aperture formed in theupper part of the bracket. \Vhen the upper end of the spring is inengagement with the upper groove E, the lower end of the pin will beheld in engagement with the groove B and a longitudinal movement will beimparted to the shaft, which movement is permitted by the longitudinalgroove in the opposite end of the shaft in which the spline of thegear-wheel B loosely rests. By lifting the pin so that the upper end ofthe pin will engage the lower groove on the pin the latter will be heldout of engagement with the groove, and the shaft can be quickly andfreely adjusted by sliding it to the desired position. The shallow traysIt will be further noted that the collars C and C are slidable on theshaft B and are secured in their adjusted position by means of thecotter-pins (1*, carried by each collar. This construction permits thespacing apart of the collars.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination With a receptacle, a rotatable shaft passingtherethrough, a double spiral groove on said shaft exterior of thereceptacle, a stationary pin adapted to engage said groove, and armscarried by the shaft and adapted to rotate Within the receptacle,substantially as described.

2. A device of the kind described comprisinga receptacle, a shaftpassing therethrough,
